KUSA - Mother Prioress Dolores may have gotten to kiss Elvis, but her life since then has been dominated by a much bigger love: God.

"I think the only thing you can know is God and his heart," she said. "It's what comes to you in love. If you fall in love with someone, you know what happens, and I think that's what happened to me."

Mother Dolores was once Dolores Hart, a 1960s starlet who famously starred opposite of Montgomery Clift, Robert Wagner and Elvis Presley - twice.

But at the peak of her career, she stunned Hollywood by quitting acting and entering into religious life as a Catholic nun.

"You have everything at your feet, and everything is given to you" she said of her time in Hollywood. "And then you realize there's something deeper, you know there's something better than this stuff, and that takes you, all of the other problems work out, but the deeper thing to note is that God is more, he made everything. He made Cadillacs."

Hart first entered the Abbey of Regina Laudis in 1959 at the suggestion of a friend, when she was trying to recharge for a role. She returned to Hollywood, but kept in touch when the nuns, who encouraged her to join.

"I think the best part is the friendships that you can make," Hart said of her life at the abbey. "In that order, hospitality is one of the main things, and there's so many people that come speak to us, and for us, it's a treasure because you really get to understand and know the human race and that people are wonderful."

She says acting did have its share of perks.

"I loved to be able to tell a story," she said.

And as for Elvis - the man who she had famously kissed twice - Hart had nothing but positive things to say.

"He was a doll. Nobody knew. The first time I met him he stood up and said 'How do you do, Ms. Dolores?"' she said. "[He was] a southern gentleman, so well-trained by his mother."

Hart has released a book about her experience "The Ear of the Heart: An actress' Journey From Hollywood to Holy Vows."
